Techimp is your premierpartner for diagnosis andcondition based

maintenance of electricalsystems.In the last years many economicsectors have been deeplyrestructured under a wave ofcompetition and privatization. As aresult, operators need to be ableto face shrinking revenues andlimited investment possibilities.Maintenance practices have been,consequently, changed radically.Industries, especially those withvery large hourly revenues (e.g.,Upstream-oil industry, MidstreamDownstream), must have a highlyreliable electrical plants to avoidproduction stops which may implyconsiderable profit losses.Electrical assets often ensureoperation of critical processes inindustrial plants: breakdown ofsuch assets may have seriousconsequences in terms of

economic losses and, sometimes,operator safety.Techimp's experience indiagnosis of electrical systems inoil&gas industry started in 90's.Since then a growing number ofpartners exploits our worldwideexperience.The core of the approach is basedon an innovative technology for online PARTIAL DISCHARGE (PD)detection and analysis. Otherquantities are detected, such asdissolved gas in oil (online DGA),vibrations (online VIB), tano (online

tal, temperature, power quality,environmental conditions.The excellence of Techimptechnology is experiencedmainly in on-line monitoring,where noise and disturbancerejection becomes the addedvalue with respect to any othertechnology.

As a matter of fact, Techimpon-line monitoring systemsrepresent the ideal andultimate solution for theCondition Base Maintenance(CBM) of electrical apparatus.

Diagnostic for Oil & Gas InstallationsMotors, Pumps, Generators, Cables, Transformers, Switchgears are the mostcritical components in a electrical subsystem of Oil&Gas Plants and, in fact, their failureis among the first causes for system outages in Offshore Production Platforms, Oil/GasFields, Refineries, Petrochemical Plants & Power Generation Plants.After years of advanced researches, laboratory and on-field tests, Techimp hasdeveloped an on-line powerful and effective technology which supports the assetmanager decisions to manage electrical subsystems in a cost-saving way.Reduction of overall maintenance costs and better diagnostic coverage, exploitingsynergies between information provided by different diagnostic techniques and chosenreliability level in monitored systems, are the strength of the Techimp approach.Techimp offers a complete system for on-line condition assessment by means ofcontinuous monitoring of the following parameters:

Global Monitoring&Subsystems

Partial discharge (PO) Dissolved Gas Analysis (DGA) Tangent delta (ta) Vibration Analysis (VIB) Distributed Temperature Sensors (DTS)

One of our solutions: PO monitor ing (POM) in a generation plant supplying aoi/&gas field.The system is aimed at acquiring, processing and analysing partial discharge pulsesoriginated in apparatus supplying the energy to the oi l&gas field, that is: Generators (G) HV/MV Cables (C) Transformers (T ) MV Motors (M)All the diagnostic system works on line and is connected to a control room. Thediagnostic system is able to send remotely awards when pre-selected thresholdsare overcome.

Measurements can be carried out both on-line with the equipment under test suppliedby the electric network and off-line, with the electrical system supplied by an externalvoltage source. Thus, off-line tests can be carried out only periodically, when the plantoperation is stopped. In addition, extra costs, related to the acquisition of the externalvoltage source, will occur.

Therefore, the ideal solution for the prevention of electrical asset failures is on-line monitoring.

For on line Permanent Monitoring, all sensors and theacquisition units are permanently installed, so that acontinuous monitoring can be performed.PO, DGA, t8, VIB, DTS are connected to one acquisitionunit; an Ethernet or wireless connection allows completeremote supervision and control to be carried out. Artificialintelligence is implemented in the detector able to provideremote alert in case pre-selected conditions are exceeded.

For on line Periodic Assessment, an acquisition unit isconnected to permanently installed (or clamped) sensors fromtime to time. In this case periodic measurements can be carriedout without the need of turning the electrical asset out ofservice. The periodic assessment will be carried out with afrequency based on the state of each apparatus under test. Thisrequires the use of a suitable database, also provided byTechimp.

PARTIAL DISCHARGE (PO)Insulation breakdown generally is the main cause of outage of electricalapparatus.Degradation phenomena associated with defects existing in theinsulation system, introduced during on field assembly of an electr icalapparatus or grown by insulation aging, can be diagnosed often bymeans of Partial Discharge (PO)measurement and analysis.
